/Engine/Source/Runtime/Core/Public/Compression/CompressedBuffer.h
The compressor and compression level may differ from those specified when creating the buffer because an incompressible buffer is stored with no compression. Parameters cannot be accessed if this is null or uses a method other than Oodle, in which case this returns false.
True if parameters were written, otherwise false.
